888425 ÷ 53 
The aim is to understand the frequency of 53 in 888425.

Step 1:
53 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 53

Going ahead to step 2:
When dividing 88 by 53, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 35 after subtracting 53 from 88.
Fetch the next digit (8) from the dividend, attach it to 35 and continue: 358 / 53

Step 3:
53 goes into 358 6 times with a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 318 from 358 leaves us with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 53

Step 4:
The number 53 fits into 404 7 times, leaving a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 167.0
Deduct 371 from 404 and we're left with 33.
Take the next digit (2) from the dividend and append it to 33, then repeat: 332 / 53

Advancing to step 5:
The number 53 fits into 332 6 times, leaving a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 1676.0
Subtracting 318 from 332 leaves us with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 53

Going ahead to step 6:
If we divide 145 by 53, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 16762.0
The remainder is 39 after subtracting 106 from 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
53 can be fit into 390 7 times, resulting in a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 16762.7
The remainder is 19 after subtracting 371 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 8:
53 can be fit into 190 3 times, resulting in a remainder of 31.
The next digit of our result is 3. 
Result so far: 16762.73
Subtract 159 from 190 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 9:
If we divide 310 by 53, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 16762.735
If we subtract 265 from 310, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 10:
If we divide 450 by 53, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 16762.7358
Deduct 424 from 450 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
53 can be fit into 260 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 16762.73584
If we subtract 212 from 260, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
53 can be fit into 480 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 16762.735849
Deduct 477 from 480 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
If we divide 30 by 53, we get 0 and a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 16762.735849
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 14:
The number 53 fits into 300 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 16762.73584905
Deduct 265 from 300 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 16762.73584905, with a leftover of 3.5e-08.
